Today, a bushy filament of magnetism is snaking more than 150,000 km from end to end, over the sun's northeastern limb.
I like the method used by dedo/Andréa to enhance the sun disk, here in H alpha. Best seen in B&W.
Under the double sketch I try to represent the active region. This was a very rapid and brillant evolution.

It's simply better and better every time I see your beautiful work, Michel. The frame sequence of the flare is outstanding observational work!

Michel,
Excellent full disk Ha sketch. That big fat filament is impressive. I like your prominence sequence, too. I believe that type of prom is called a surge--they are usually quite bright.
